Mission considerations for multidiscipline applications payloads

Special considerations in the planning of Space Shuttle missions for multidiscipline applications are summarized. Selection of orbits and launch times, the optimum operations schedule and viewing opportunities for a given mission are discussed. Trade-offs between the limitations of a mission-peculiar sensor mount and time requirements for sensor retraction/deployment operations in the planning of the payload mounting design are considered. It is suggested that payloads which are largely automated or whose operation is not orbit-time sensitive be considered as possible 'fill-ins' between opportunity-constrained operations. Sequential scheduling of payload operations and delayed real-time data transmission may be means of avoiding RF interference between payloads and with Orbiter communications links, and of maintaining resource demands within manageable levels.
